Burnt missive

 is an item in Tyranny.

Description
The contents of this missive are obscured by the page's burnt edges, but you can tell that Graven Ashe was the intended recipient. The sender makes a plea for assistance, as she doesn't believe her garrison in the Blade Grave has sufficient troops to hold their location.
